Thanks for bringing this up here. I changed the notice in my bzr tree
to match the below wording and removed the YnPrompt() for now. I agree
that it was not useful for package maintained on alioth with svn where
no good way for branching from there exists.
The rational for the change in the first place was to make it obvious
for people who modify packages that are maintained in a VCS that just
apt-get source, change, upload causes problems. It means the VCS gets
out of sync with the archive and that the maintainer have to manually
sync that by appying the debdiff. This was done in the past and lead
to a number of bugs when the merging with the archive was done at some
later point, the diff did not apply cleanly anymore etc.
So for package maintained with bzr in launchpad.net I would like to
see people using bzr to branch the package and then upload their
branch so that the maintainer can easily merge the changes. Having
this warning is a first step, I'm just afraid that without a prompt
the warning will be ignored.
I understand that the tools are currently not perfect (also
bzr-buildpackage and bzr-unpack are quite good already) and that we
lack strong policies on the branch layout etc. But as more and more
package move towards maintainance in a VCS (hey gnome!) this problem
is something that will become more pressing in the future.
